There are no available data on LORBRENA use in pregnant women. Administration of lorlatinib to pregnant rats and rabbits by oral gavage during the period of organogenesis resulted in malformations, increased post-implantation loss, and abortion at maternal exposures that were equal to or less than the human exposure at the recommended dose of 100 mg once daily based on AUC (see Data ) . Advise a pregnant woman of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies are 2 to 4% and 15 to 20%, respectively. Data Animal Data Preliminary embryo-fetal development studies investigating the administration of lorlatinib during the period of organogenesis were conducted in rats and rabbits. In rabbits, lorlatinib administration resulted in abortion and total loss of pregnancy at doses of 15 mg/kg (approximately 3 times the human exposure at the recommended dose of 100 mg) or greater. At a dose of 4 mg/kg (approximately 0.6 times the human exposure at the recommended dose of 100 mg) toxicities included increased post-implantation loss and malformations including rotated limbs, malformed kidneys, domed head, high arched palate, and dilation of the cerebral ventricles. In rats, administration of lorlatinib resulted in total loss of pregnancy at doses of 4 mg/kg (approximately 5 times the human exposure at the recommended dose of 100 mg) or greater. At a dose of 1 mg/kg (approximately equal to the human exposure at the recommended dose of 100 mg) there was increased post-implantation loss, decreased fetal body weight, and malformations including gastroschisis, rotated limbs, supernumerary digits, and vessel abnormalities."],"description":["11 DESCRIPTION LORBRENA (lorlatinib) is a kinase inhibitor for oral administration.

Patients were required to have an ECOG performance status of 0–2 and ALK-positive NSCLC as identified by the VENTANA ALK (D5F3) CDx assay. Neurologically stable patients with treated or untreated asymptomatic CNS metastases, including leptomeningeal metastases, were eligible. Patients were required to have finished radiation therapy, at least 2 weeks (for stereotactic or partial radiation) or 4 weeks (for whole brain irradiation) prior to randomization. Patients with severe acute or chronic psychiatric conditions, including recent (within the past year) or active suicidal ideation or behavior, were excluded. Patients were randomized 1:1 to receive LORBRENA 100 mg orally once daily or crizotinib 250 mg orally twice daily. Randomization was stratified by ethnic origin (Asian vs. non-Asian) and the presence or absence of CNS metastases at baseline. Treatment on both arms was continued until disease progression or unacceptable toxicity. The major efficacy outcome measure was progression-free survival (PFS) as determined by Blinded Independent Central Review (BICR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (v1.1). Additional efficacy outcome measures were overall survival (OS) and tumor assessment related data by BICR, including overall response rate (ORR), and duration of response (DOR). In patients with measurable CNS metastases at baseline, additional outcome measures were intracranial overall response rate (IC-ORR) and intracranial duration of response (IC-DOR) by BICR. A total of 296 patients were randomized to LORBRENA (n=149) or crizotinib (n=147). The demographic characteristics of the overall study population were: median age 59 years (range: 26 to 90 years), age ≥65 years (35%), 59% female, 49% White, 44% Asian, and 0.3% Black. The ECOG performance status at baseline was 0 or 1 in 96% of patients. The majority of patients had adenocarcinoma (95%) and never smoked (59%). CNS metastases were present in 26% (n=78) of patients: of these, 30 patients had measurable CNS lesions. Efficacy results from Study B7461006 as assessed by BICR are summarized in Table 6 and Figure 1. Results demonstrated a significant improvement in PFS for the LORBRENA arm over the crizotinib arm. At the data cutoff point OS data was not mature.

Patients included in this subgroup were required to have metastatic disease with at least 1 measurable target lesion according to RECIST v1.1, ECOG performance status of 0 to 2, and documented ALK rearrangement in tumor tissue as determined by fluorescence in situ hybridization (FISH) assay or by Immunohistochemistry (IHC), and received LORBRENA 100 mg orally once daily. Patients with asymptomatic CNS metastases, including patients with stable or decreasing steroid use within 2 weeks prior to study entry, were eligible. Patients with severe, acute, or chronic psychiatric conditions including suicidal ideation or behavior were excluded. In addition, for patients with ALK-positive metastatic NSCLC, the extent and type of prior treatment was specified for each individual cohort (see Table 8 ). The major efficacy outcome measures were ORR and intracranial ORR, according to RECIST v1.1, as assessed by Independent Central Review (ICR) committee. Data were pooled across all subgroups listed in Table 8. Additional efficacy outcome measures included DOR, and intracranial DOR. A total of 215 patients were enrolled across the subgroups in Table 8. The distribution of patients by type and extent of prior therapy is provided in Table 8. The demographic characteristics across all 215 patients were: 59% female, 51% White, 34% Asian, and the median age was 53 years (29 to 85 years) with 18% of patients ≥65 years. The ECOG performance status at baseline was 0 or 1 in 96% of patients. All patients had metastatic disease and 95% had adenocarcinoma.

Cardiac Electrophysiology In 295 patients who received LORBRENA at the recommended dosage of 100 mg once daily and had an ECG measurement in Study B7461001, the maximum mean change from baseline for PR interval was 16.4 ms (2-sided 90% upper confidence interval [CI] 19.4 ms). Among the 284 patients with PR interval <200 ms at baseline, 14% had PR interval prolongation ≥200 ms after starting LORBRENA. The prolongation of PR interval occurred in a concentration-dependent manner. Atrioventricular block occurred in 1% of patients. In 275 patients who received LORBRENA at the recommended dosage in the activity-estimating portion of Study B7461001, no large mean increases from baseline in the QTcF interval (i.e., >20 ms) were detected."],"pharmacokinetics":["12.3 Pharmacokinetics At the recommended dosage, the mean (coefficient of variation [CV] %) maximum plasma concentration (C max ) is 577 ng/mL (42%) and the AUC 0-24h is 5,650 ng·h/mL (39%). Steady-state lorlatinib C max increases proportionally and AUC increased slightly less than proportionally over the dose range of 10 mg to 200 mg orally once daily (0.1 to 2 times the recommended dosage). Absorption The median lorlatinib T max is 1.2 hours (0.5 to 4 hours) following a single oral 100 mg dose and 2 hours (0.5 to 23 hours) following 100 mg orally once daily at steady‑state. The mean absolute bioavailability is 81% (90% CI 76%, 86%). Effect of Food No clinically significant differences in lorlatinib pharmacokinetics were observed following administration of a high fat, high calorie meal (approximately 1000 calories with 150 calories from protein, 250 calories from carbohydrate, and 500 to 600 calories from fat). Distribution Lorlatinib is 66% bound to plasma proteins, in vitro. The blood-to-plasma ratio is 0.99, in vitro. Elimination The mean plasma half‑life (t ½ ) of lorlatinib was 24 hours (40%) after a single oral 100 mg dose of LORBRENA. The mean oral clearance (CL/F) was 11 L/h (35%) following a single oral 100 mg dose and increased to 18 L/h (39%) at steady‑state, suggesting autoinduction. Metabolism Lorlatinib is metabolized primarily by CYP3A4 and UGT1A4, with minor contribution from CYP2C8, CYP2C19, CYP3A5, and UGT1A3. In plasma, a benzoic acid metabolite (M8) of lorlatinib resulting from the oxidative cleavage of the amide and aromatic ether bonds of lorlatinib accounted for 21% of the circulating radioactivity. The oxidative cleavage metabolite, M8, is pharmacologically inactive. Excretion Following a single oral 100 mg dose of radiolabeled lorlatinib, 48% of the radioactivity was recovered in urine (<1% as unchanged) and 41% in feces (about 9% as unchanged). Specific Populations No clinically significant differences in lorlatinib pharmacokinetics were observed based on age (19 to 85 years), sex, race/ethnicity (52% White, 8% Black, 27% Asian), body weight (32-156 kg), CL cr 30 to 89 mL/min (estimated by Cockcroft Gault), mild (total bilirubin ≤ ULN and AST > ULN or total bilirubin > 1 to 1.5 × ULN and any AST) to moderate (Child-Pugh B) hepatic impairment, or metabolizer phenotypes for CYP3A5 and CYP2C19. Patients with Moderate or Severe Hepatic Impairment Following administration of a single oral 100 mg dose of LORBRENA, lorlatinib AUC increased 1.1-fold in non-cancer subjects with moderate hepatic impairment (Child-Pugh B) and 1.8-fold in non-cancer subjects with severe hepatic impairment (Child-Pugh C). Patients with Renal Impairment Following administration of a single oral 100 mg dose of LORBRENA, lorlatinib AUC increased 1.4-fold in subjects with CL cr 15 to <30 mL/min (estimated by Cockcroft Gault). The pharmacokinetics of lorlatinib have not been studied in patients with end-stage renal disease requiring hemodialysis. Drug Interaction Studies Clinical Studies and Model-Informed Approaches Strong CYP3A Inducers : Rifampin (a strong CYP3A inducer that also activates PXR) 600 mg once daily for 8 days (Days 1 to 8) coadministered with a single oral 100 mg dose of LORBRENA on Day 8 reduced the mean lorlatinib AUC by 85% and C max by 76%. Grade 2 to 4 increases in ALT or AST occurred within 3 days. Grade 4 ALT or AST elevations occurred in 50%, Grade 3 ALT or AST elevations in 33%, and Grade 2 ALT or AST elevations occurred in 8% of subjects. ALT and AST returned to within normal limits within 7 to 34 days (median 15 days). Moderate CYP3A Inducers : Modafinil (a moderate CYP3A inducer) decreased lorlatinib AUC by 23% and C max by 22% of a single oral 100 mg dose of LORBRENA. Strong CYP3A Inhibitors : Itraconazole (a strong CYP3A inhibitor) increased lorlatinib AUC 1.4-fold and C max 1.2-fold of a single oral 100 mg dose of LORBRENA. Fluconazole : Fluconazole is predicted to increase lorlatinib AUC 1.6-fold and C max 1.3-fold following concomitant oral administration of 100 mg of LORBRENA once daily and 200 mg fluconazole once daily. Moderate CYP3A Inhibitors : No clinically significant effect on lorlatinib pharmacokinetics is predicted when used concomitantly with verapamil or erythromycin. CYP3A Substrates : LORBRENA 150 mg orally once daily for 15 days decreased AUC by 64% and C max by 50% of a single oral 2 mg dose of midazolam (a sensitive CYP3A substrate). CYP2B6 Substrates : LORBRENA 100 mg orally once daily for 15 days decreased AUC by 25% and C max by 27% of a single oral 100 mg dose of bupropion (a sensitive CYP2B6 substrate). CYP2C9 Substrates : LORBRENA 100 mg orally once daily for 15 days decreased AUC by 43% and C max by 15% of a single oral 100 mg dose of tolbutamide (a sensitive CYP2C9 substrate). UGT1A Substrates : LORBRENA 100 mg orally once daily for 15 days decreased AUC by 45% and C max by 28% of a single oral 100 mg dose of acetaminophen (a UGT1A substrate). P-gp Substrates : LORBRENA 100 mg orally once daily for 15 days decreased AUC by 67% and C max by 63% of a single oral 60 mg dose of fexofenadine (a P-gp substrate). Acid-Reducing Agents : Concomitant use of a proton pump inhibitor, rabeprazole, did not have a clinically significant effect on lorlatinib pharmacokinetics. In Vitro Studies CYP Enzymes : Lorlatinib is a time-dependent inhibitor as well as an inducer of CYP3A and activates PXR, with the net effect in vivo being induction. Lorlatinib induces CYP2B6 and activates the human constitutive androstane receptor (CAR). Lorlatinib and the major circulating metabolite, M8, do not inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, or CYP2D6. M8 does not inhibit CYP3A. M8 does not induce CYP1A2, CYP2B6, or CYP3A. UDP-glucuronosyltransferase (UGT) : Lorlatinib and M8 do not inhibit UGT1A1, UGT1A4, UGT1A6, UGT1A9, UGT2B7, or UGT2B15. Transporter Systems : Lorlatinib is an inhibitor of P-gp and activates PXR (potential to induce P-gp), with the net effect in vivo being induction. Lorlatinib inhibits OCT1, OAT3, MATE1, and intestinal BCRP. Lorlatinib does not inhibit OATP1B1, OATP1B3, OAT1, OCT2, MATE2K, or systemic BCRP. M8 does not inhibit P‑gp, BCRP, OATP1B1, OATP1B3, OAT1, OAT3, OCT1, OCT2, MATE1, or MATE2K."],"adverse_reactions":["6 ADVERSE REACTIONS The following adverse reactions are described elsewhere in the labeling: • Risk of Serious Hepatotoxicity with Concomitant Use of Strong CYP3A Inducers [see Warnings and Precautions (5.1) ] • Central Nervous System Effects [see Warnings and Precautions (5.2) ] • Hyperlipidemia [see Warnings and Precautions (5.3) ] • Atrioventricular Block [see Warnings and Precautions (5.4) ] • Interstitial Lung Disease/Pneumonitis [see Warnings and Precautions (5.5) ] • Hypertension [see Warnings and Precautions (5.6) ] • Hyperglycemia [see Warnings and Precautions (5.7) ] Most common (incidence ≥20%) adverse reactions and Grade 3–4 laboratory abnormalities are edema, peripheral neuropathy, weight gain, cognitive effects, fatigue, dyspnea, arthralgia, diarrhea, mood effects, hypercholesterolemia, hypertriglyceridemia, and cough.

The median duration of exposure to LORBRENA was 12.5 months (1 day to 35 months) and 52% received LORBRENA for ≥12 months. Patient characteristics were: median age of 53 years (19 to 85 years), age ≥65 years (18%), female (58%), White (49%), Asian (37%), and ECOG performance status 0 or 1 (96%). The most frequent (≥20%) adverse reactions were edema, peripheral neuropathy, cognitive effects, dyspnea, fatigue, weight gain, arthralgia, mood effects, and diarrhea. Of the worsening laboratory values occurring in ≥20% of patients, the most frequent were hypercholesterolemia, hypertriglyceridemia, anemia, hyperglycemia, increased AST, hypoalbuminemia, increased ALT, increased lipase, and increased alkaline phosphatase. Serious adverse reactions occurred in 32% of the 295 patients; the most frequently reported serious adverse reactions were pneumonia (3.4%), dyspnea (2.7%), pyrexia (2%), mental status changes (1.4%), and respiratory failure (1.4%).

The overall antitumor activity of lorlatinib in in vivo models was dose-dependent and correlated with inhibition of ALK phosphorylation. 12.2 Pharmacodynamics Exposure-response relationships for Grade 3 or 4 hypercholesterolemia and for any Grade 3 or 4 adverse reaction were observed at steady-state exposures achieved at the recommended dosage, with higher probability of the occurrence of adverse reactions with increasing lorlatinib exposure. Cardiac Electrophysiology In 295 patients who received LORBRENA at the recommended dosage of 100 mg once daily and had an ECG measurement in Study B7461001, the maximum mean change from baseline for PR interval was 16.4 ms (2-sided 90% upper confidence interval [CI] 19.4 ms). Among the 284 patients with PR interval <200 ms at baseline, 14% had PR interval prolongation ≥200 ms after starting LORBRENA. The prolongation of PR interval occurred in a concentration-dependent manner. Atrioventricular block occurred in 1% of patients. In 275 patients who received LORBRENA at the recommended dosage in the activity-estimating portion of Study B7461001, no large mean increases from baseline in the QTcF interval (i.e., >20 ms) were detected. 12.3 Pharmacokinetics At the recommended dosage, the mean (coefficient of variation [CV] %) maximum plasma concentration (C max ) is 577 ng/mL (42%) and the AUC 0-24h is 5,650 ng·h/mL (39%). Steady-state lorlatinib C max increases proportionally and AUC increased slightly less than proportionally over the dose range of 10 mg to 200 mg orally once daily (0.1 to 2 times the recommended dosage). Absorption The median lorlatinib T max is 1.2 hours (0.5 to 4 hours) following a single oral 100 mg dose and 2 hours (0.5 to 23 hours) following 100 mg orally once daily at steady‑state. The mean absolute bioavailability is 81% (90% CI 76%, 86%). Effect of Food No clinically significant differences in lorlatinib pharmacokinetics were observed following administration of a high fat, high calorie meal (approximately 1000 calories with 150 calories from protein, 250 calories from carbohydrate, and 500 to 600 calories from fat). Distribution Lorlatinib is 66% bound to plasma proteins, in vitro. The blood-to-plasma ratio is 0.99, in vitro. Elimination The mean plasma half‑life (t ½ ) of lorlatinib was 24 hours (40%) after a single oral 100 mg dose of LORBRENA. The mean oral clearance (CL/F) was 11 L/h (35%) following a single oral 100 mg dose and increased to 18 L/h (39%) at steady‑state, suggesting autoinduction. Metabolism Lorlatinib is metabolized primarily by CYP3A4 and UGT1A4, with minor contribution from CYP2C8, CYP2C19, CYP3A5, and UGT1A3. In plasma, a benzoic acid metabolite (M8) of lorlatinib resulting from the oxidative cleavage of the amide and aromatic ether bonds of lorlatinib accounted for 21% of the circulating radioactivity. The oxidative cleavage metabolite, M8, is pharmacologically inactive. Excretion Following a single oral 100 mg dose of radiolabeled lorlatinib, 48% of the radioactivity was recovered in urine (<1% as unchanged) and 41% in feces (about 9% as unchanged). Specific Populations No clinically significant differences in lorlatinib pharmacokinetics were observed based on age (19 to 85 years), sex, race/ethnicity (52% White, 8% Black, 27% Asian), body weight (32-156 kg), CL cr 30 to 89 mL/min (estimated by Cockcroft Gault), mild (total bilirubin ≤ ULN and AST > ULN or total bilirubin > 1 to 1.5 × ULN and any AST) to moderate (Child-Pugh B) hepatic impairment, or metabolizer phenotypes for CYP3A5 and CYP2C19. Patients with Moderate or Severe Hepatic Impairment Following administration of a single oral 100 mg dose of LORBRENA, lorlatinib AUC increased 1.1-fold in non-cancer subjects with moderate hepatic impairment (Child-Pugh B) and 1.8-fold in non-cancer subjects with severe hepatic impairment (Child-Pugh C). Patients with Renal Impairment Following administration of a single oral 100 mg dose of LORBRENA, lorlatinib AUC increased 1.4-fold in subjects with CL cr 15 to <30 mL/min (estimated by Cockcroft Gault). The pharmacokinetics of lorlatinib have not been studied in patients with end-stage renal disease requiring hemodialysis. Drug Interaction Studies Clinical Studies and Model-Informed Approaches Strong CYP3A Inducers : Rifampin (a strong CYP3A inducer that also activates PXR) 600 mg once daily for 8 days (Days 1 to 8) coadministered with a single oral 100 mg dose of LORBRENA on Day 8 reduced the mean lorlatinib AUC by 85% and C max by 76%. Grade 2 to 4 increases in ALT or AST occurred within 3 days. Grade 4 ALT or AST elevations occurred in 50%, Grade 3 ALT or AST elevations in 33%, and Grade 2 ALT or AST elevations occurred in 8% of subjects. ALT and AST returned to within normal limits within 7 to 34 days (median 15 days). Moderate CYP3A Inducers : Modafinil (a moderate CYP3A inducer) decreased lorlatinib AUC by 23% and C max by 22% of a single oral 100 mg dose of LORBRENA. Strong CYP3A Inhibitors : Itraconazole (a strong CYP3A inhibitor) increased lorlatinib AUC 1.4-fold and C max 1.2-fold of a single oral 100 mg dose of LORBRENA. Fluconazole : Fluconazole is predicted to increase lorlatinib AUC 1.6-fold and C max 1.3-fold following concomitant oral administration of 100 mg of LORBRENA once daily and 200 mg fluconazole once daily. Moderate CYP3A Inhibitors : No clinically significant effect on lorlatinib pharmacokinetics is predicted when used concomitantly with verapamil or erythromycin. CYP3A Substrates : LORBRENA 150 mg orally once daily for 15 days decreased AUC by 64% and C max by 50% of a single oral 2 mg dose of midazolam (a sensitive CYP3A substrate). CYP2B6 Substrates : LORBRENA 100 mg orally once daily for 15 days decreased AUC by 25% and C max by 27% of a single oral 100 mg dose of bupropion (a sensitive CYP2B6 substrate). CYP2C9 Substrates : LORBRENA 100 mg orally once daily for 15 days decreased AUC by 43% and C max by 15% of a single oral 100 mg dose of tolbutamide (a sensitive CYP2C9 substrate). UGT1A Substrates : LORBRENA 100 mg orally once daily for 15 days decreased AUC by 45% and C max by 28% of a single oral 100 mg dose of acetaminophen (a UGT1A substrate). P-gp Substrates : LORBRENA 100 mg orally once daily for 15 days decreased AUC by 67% and C max by 63% of a single oral 60 mg dose of fexofenadine (a P-gp substrate). Acid-Reducing Agents : Concomitant use of a proton pump inhibitor, rabeprazole, did not have a clinically significant effect on lorlatinib pharmacokinetics. In Vitro Studies CYP Enzymes : Lorlatinib is a time-dependent inhibitor as well as an inducer of CYP3A and activates PXR, with the net effect in vivo being induction. Lorlatinib induces CYP2B6 and activates the human constitutive androstane receptor (CAR). Lorlatinib and the major circulating metabolite, M8, do not inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, or CYP2D6. M8 does not inhibit CYP3A. M8 does not induce CYP1A2, CYP2B6, or CYP3A. UDP-glucuronosyltransferase (UGT) : Lorlatinib and M8 do not inhibit UGT1A1, UGT1A4, UGT1A6, UGT1A9, UGT2B7, or UGT2B15. Transporter Systems : Lorlatinib is an inhibitor of P-gp and activates PXR (potential to induce P-gp), with the net effect in vivo being induction. Lorlatinib inhibits OCT1, OAT3, MATE1, and intestinal BCRP. Lorlatinib does not inhibit OATP1B1, OATP1B3, OAT1, OCT2, MATE2K, or systemic BCRP. M8 does not inhibit P‑gp, BCRP, OATP1B1, OATP1B3, OAT1, OAT3, OCT1, OCT2, MATE1, or MATE2K."],"indications_and_usage":["1 INDICATIONS AND USAGE LORBRENA ® is indicated for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) whose tumors are anaplastic lymphoma kinase (ALK)-positive as detected by an FDA-approved test.

Grade 3 or 4 elevations in total cholesterol occurred in 18% and Grade 3 or 4 elevations in triglycerides occurred in 19% of the 476 patients who received 100 mg LORBRENA once daily. The median time to onset was 15 days for both hypercholesterolemia and hypertriglyceridemia. Approximately 4% and 7% of patients required temporary discontinuation and 1% and 3% of patients required dose reduction of LORBRENA for elevations in cholesterol and in triglycerides in Study B7461001 and Study B7461006, respectively. Eighty-three percent of patients required initiation of lipid-lowering medications, with a median time to onset of start of such medications of 17 days. Initiate or increase the dose of lipid-lowering agents in patients with hyperlipidemia. Monitor serum cholesterol and triglycerides before initiating LORBRENA, 1 and 2 months after initiating LORBRENA, and periodically thereafter. Withhold and resume at the same dose for the first occurrence; resume at the same or a reduced dose of LORBRENA for recurrence based on severity [see Dosage and Administration (2.3) ]. 5.4 Atrioventricular Block PR interval prolongation and atrioventricular (AV) block can occur in patients receiving LORBRENA [see Adverse Reactions (6.1) , Clinical Pharmacology (12.2) ]. In 476 patients who received 100 mg LORBRENA once daily and who had a baseline electrocardiography (ECG), 1.9% experienced AV block and 0.2% experienced Grade 3 AV block and underwent pacemaker placement. Monitor ECG prior to initiating LORBRENA and periodically thereafter. Withhold and resume at a reduced dose or at the same dose in patients who undergo pacemaker placement. Permanently discontinue for recurrence in patients without a pacemaker [see Dosage and Administration (2.3) ] . 5.5 Interstitial Lung Disease/Pneumonitis Severe or life-threatening pulmonary adverse reactions consistent with interstitial lung disease (ILD)/pneumonitis can occur with LORBRENA. ILD/pneumonitis occurred in 1.9% of patients who received 100 mg LORBRENA once daily, including Grade 3 or 4 ILD/pneumonitis in 0.6% of patients. Four patients (0.8%) discontinued LORBRENA for ILD/pneumonitis. Promptly investigate for ILD/pneumonitis in any patient who presents with worsening of respiratory symptoms indicative of ILD/pneumonitis (e.g., dyspnea, cough, and fever). Immediately withhold LORBRENA in patients with suspected ILD/pneumonitis. Permanently discontinue LORBRENA for treatment-related ILD/pneumonitis of any severity [see Dosage and Administration (2.3) ] . 5.6 Hypertension Hypertension can occur in patients receiving LORBRENA [see Adverse Reactions (6.1) ] . Hypertension occurred in 13% of patients who received 100 mg LORBRENA once daily, including Grade 3 or 4 in 6% of patients. The median time to onset of hypertension was 6.4 months (1 day to 2.8 years), and 2.3% of patients temporarily discontinued LORBRENA for hypertension. Control blood pressure prior to initiation of LORBRENA. Monitor blood pressure after 2 weeks and at least monthly thereafter during treatment with LORBRENA. Withhold and resume at a reduced dose or permanently discontinue LORBRENA based on severity [see Dosage and Administration (2.3) ] . 5.7 Hyperglycemia Hyperglycemia can occur in patients receiving LORBRENA [see Adverse Reactions (6.1) ] . Hyperglycemia occurred in 9% of patients who received 100 mg LORBRENA, including Grade 3 or 4 in 3.2% of patients. The median time to onset of hyperglycemia was 4.8 months (1 day to 2.9 years), and 0.8% of patients temporarily discontinued LORBRENA for hyperglycemia. Assess fasting serum glucose prior to initiation of LORBRENA and monitor periodically thereafter. Withhold and resume at a reduced dose or permanently discontinue LORBRENA based on severity [see Dosage and Administration (2.3) ] . 5.8 Embryo-Fetal Toxicity Based on findings from animal studies and its mechanism of action, LORBRENA can cause fetal harm when administered to a pregnant woman. Administration of lorlatinib to pregnant rats and rabbits by oral gavage during the period of organogenesis resulted in malformations, increased post-implantation loss, and abortion at maternal exposures that were equal to or less than the human exposure at the recommended dose of 100 mg once daily based on area under the curve (AUC). Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use an effective non-hormonal method of contraception, since LORBRENA can render hormonal contraceptives ineffective, during treatment with LORBRENA and for at least 6 months after the final dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with LORBRENA and for 3 months after the final dose [see Drug Interactions (7.2) , Use in Specific Populations (8.1 , 8.3) , Nonclinical Toxicology (13.1) ] ."],"clinical_studies_table":["

Lorlatinib was aneugenic in an in vitro assay in human lymphoblastoid TK6 cells and positive for micronuclei formation in vivo in the bone marrow of rats. Lorlatinib was not mutagenic in an in vitro bacterial reverse mutation (Ames) assay. Dedicated fertility studies were not conducted with lorlatinib. Findings in male reproductive organs occurred in repeat-dose toxicity studies and included lower testicular, epididymal, and prostate weights; testicular tubular degeneration/atrophy; prostatic atrophy; and/or epididymal inflammation at 15 mg/kg/day and 7 mg/kg/day in rats and dogs, respectively (approximately 8 and 2 times, respectively, the human exposure at the recommended dose of 100 mg based on AUC). The effects on male reproductive organs were reversible. 13.2 Animal Toxicology and/or Pharmacology Distended abdomen, skin rash, and increased cholesterol and triglycerides occurred in animals. These findings were accompanied by hyperplasia and dilation of the bile ducts in the liver and acinar atrophy of the pancreas in rats at 15 mg/kg/day and in dogs at 2 mg/kg/day (approximately 8 and 0.5 times, respectively, the human exposure at the recommended dose of 100 mg based on AUC).

"],"spl_patient_package_insert":["PATIENT INFORMATION LORBRENA (lor-BREN-ah) (lorlatinib) tablets This Patient Information has been approved by the U.S. Food and Drug Administration. Revised: January 2026 What is the most important information I should know about LORBRENA? LORBRENA can cause serious side effects, including: • Liver problems due to interactions with other medicines. Liver problems can be severe. It is important to know what medicines not to take during treatment with LORBRENA. See “ Tell your healthcare provider about all the medicines you take, including .” • Central nervous system (CNS) effects. CNS effects can be severe. Tell your healthcare provider if you get any new or worsening symptoms of CNS effects, including: o problems with thinking, such as forgetfulness or confusion o changes in mood, such as depression and thoughts about suicide or dying o psychotic effects, such as seeing or hearing things that are not real (hallucinations) o seizures o changes in speech o changes in sleep • Increases in the cholesterol and triglycerides (lipid) levels in your blood. Most people will get an increase in the lipid levels in their blood during treatment with LORBRENA. o If you get increases in the lipid levels in your blood, your healthcare provider may start you on a new medicine or increase your dose if you are already taking a medicine to lower the lipid levels in your blood. o Your healthcare provider will do blood tests to check the lipid levels in your blood before starting treatment, 1 and 2 months after starting treatment, and during treatment with LORBRENA. • Heart problems. LORBRENA can cause very slow or abnormal heartbeats. Your healthcare provider will check your heart rhythm (electrocardiogram or EKG) before starting and during treatment with LORBRENA. In some people, these problems are severe, and you may need to get a pacemaker. Tell your healthcare provider right away if you feel dizzy or faint or have abnormal heartbeats. • Lung problems. LORBRENA can cause severe or life-threatening swelling (inflammation) of the lungs during treatment that can lead to death. Symptoms may be like those from lung cancer. Tell your healthcare provider right away if you get any new or worsening symptoms of lung problems, including trouble breathing, shortness of breath, cough, or fever. • High blood pressure (hypertension).

( 8.2 ) 8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1) ] , LORBRENA can cause embryo-fetal harm when administered to a pregnant woman. There are no available data on LORBRENA use in pregnant women. Administration of lorlatinib to pregnant rats and rabbits by oral gavage during the period of organogenesis resulted in malformations, increased post-implantation loss, and abortion at maternal exposures that were equal to or less than the human exposure at the recommended dose of 100 mg once daily based on AUC (see Data ) . Advise a pregnant woman of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies are 2 to 4% and 15 to 20%, respectively. Data Animal Data Preliminary embryo-fetal development studies investigating the administration of lorlatinib during the period of organogenesis were conducted in rats and rabbits. In rabbits, lorlatinib administration resulted in abortion and total loss of pregnancy at doses of 15 mg/kg (approximately 3 times the human exposure at the recommended dose of 100 mg) or greater. At a dose of 4 mg/kg (approximately 0.6 times the human exposure at the recommended dose of 100 mg) toxicities included increased post-implantation loss and malformations including rotated limbs, malformed kidneys, domed head, high arched palate, and dilation of the cerebral ventricles. In rats, administration of lorlatinib resulted in total loss of pregnancy at doses of 4 mg/kg (approximately 5 times the human exposure at the recommended dose of 100 mg) or greater. At a dose of 1 mg/kg (approximately equal to the human exposure at the recommended dose of 100 mg) there was increased post-implantation loss, decreased fetal body weight, and malformations including gastroschisis, rotated limbs, supernumerary digits, and vessel abnormalities. 8.2 Lactation Risk Summary There are no data on the presence of lorlatinib or its metabolites in either human or animal milk or its effects on the breastfed infant or on milk production. Because of the potential for serious adverse reactions in breastfed infants, instruct women not to breastfeed during treatment with LORBRENA and for 7 days after the final dose. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating LORBRENA [see Use in Specific Populations (8.1) ] . Contraception LORBRENA can cause embryo-fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Females Advise female patients of reproductive potential to use effective non-hormonal contraception during treatment with LORBRENA and for at least 6 months after the final dose. Advise females of reproductive potential to use a non-hormonal method of contraception, because LORBRENA can render hormonal contraceptives ineffective [see Drug Interactions (7.2) ] . Males Based on genotoxicity findings, advise males with female partners of reproductive potential to use effective contraception during treatment with LORBRENA and for at least 3 months after the final dose [see Nonclinical Toxicology (13.1) ] . Infertility Males Based on findings from animal studies, LORBRENA may transiently impair male fertility [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use The safety and effectiveness of LORBRENA in pediatric patients have not been established. 8.5 Geriatric Use Of the patients in Study B7461001 (N=295) and Study B7461006 (N=149) who received 100 mg LORBRENA orally once daily, 18% and 40% of patients, respectively, were aged 65 years or older. No clinically important differences in safety or efficacy were observed between patients aged 65 years or older and younger patients. 8.6 Hepatic Impairment In patients with severe hepatic impairment (Child-Pugh C), the recommended dosage of LORBRENA is 50 mg orally once daily [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3) ] . No dose adjustment is recommended for patients with mild (total bilirubin ≤ ULN with AST > ULN or total bilirubin >1 to 1.5 × ULN with any AST) to moderate (Child-Pugh B) hepatic impairment [see Clinical Pharmacology (12.3) ] . 8.7 Renal Impairment In patients with CL cr 15 to <30 mL/min (estimated by Cockcroft‑Gault), the recommended dosage of LORBRENA is 75 mg orally once daily [see Dosage and Administration (2.6) and Clinical Pharmacology (12.3) ] .
